In respect of tyres, I can fully understand Col's point of view.
When I was circuit racing, depending upon class, you were 'forced' to use specific brands of control tyre. In my case it was Pirelli, but on my size of bike Pirelli tyres were then dreadful to ride on. Not wanting to crash, myself and others would go to scrutineering with control tyres fitted, then swap for brands that worked. In my case Dunlop KR634's.
The concept of a control tyre with subsidised tyre price sponsorship is fine in theory, but it doesn't often work in practice. Sadly the sponsors money was more important than the riders safety.
